LIQUID-COOLING APPARATUS.

Specification of Letters Patent.

Application filed October 12, 1912.

To all whom it may concern Be it known that I, ROBERT W. CUMBER- LAND, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Liquid-Cooling Apparatus, of which the following is a specification.

This invention relates to an improved apparatus for cooling liquids and is particularly applicable for the cooling of beer.

The object of the invention is to provide an improved device of the characternamed by which the inflowing liquid will be sulo' jected to a considerable area of cooling surface to rapidly change the temperature of the same and to construct the device so that the same may be readily and thoroughly cleaned.

The invention is illustrated in the accompanying drawing wherein,

Figure 1 shows the apparatus in vertical cross-section, and Fig. 2 illustrates the baffle partition in perspective.

In the drawing the numeral, 1, designates the exterior wall of an outer receptacle; 2, the inner wall of the same and, 3, a filling of suitable non-conducting material such as saw-dust whereby to form an insulation between said walls. A cover, 4, also provided with a filling, seats on the outer receptacle and closes the same.

The outer receptacle is to form a container for both the ice, 5, and an inner liquid receptacle, 6,the latter being considerably smaller than the outer receptacle whereby to leave sufficient space between it and the inner wall, 2, for the storage of the ice. The inner liquid receptacle, 6, has a bottom, 7 front wall, 8, side walls, 9; a rear wall, 10, and a cover, 11. The rear wall, 10, has a plurality of zig-zag cooling surfaces, 12, which incline back and forth as said wall extends vertically between the bottom and the liquid-receptacle cover. By means of the zigzag formation of the rear wall an increase in cooling surface is gained and pockets are therefore provided on the exterior of the said rear wall into which the ice may be packed. The lowermost inclined surface, 13, of the rear wall extends down to the bottom, 7 of the liquid receptacle and in the present instance, at the point of joinder with the bottom there is provided a vertical partition,

14, which extends from the bottom up to the I under side of the cover, 11. This partition,

14, extends from one side wall to the other and to hold the same in place I preferably provide stop lugs, 15, on the bottom and spaced apart beads, 16, on the under side of the cover so that when the cover is in place the upper edge of the partition will be engaged by said beads and thereby held against forward or backward movement. The lower edge of the partition, 14, is provided with a series of openings, 28, which latter have position at the base of the lowermost inclined surface, 13, so that the liquid flowing down said inclined surface may pass through said openings to the front side of the partition.

It will be noted that the interposition of the partition, 14, produces in the liquid receptacle what might be termed a cooling chamber, 17 at the rear of the partition and that from said cooling chamber the liquid may pass through the bottom opening or openings in the partition to the other side of the latter. The partition carries a plurality of inclined baffle-plates, 18, on its rear side which latter project downwardly and rearwardly and extend into the zig-zag openings in the rear wall. These baffle plates extend cross-wise of the partition from one sidewall to the other so that the liquid to be cooled may be admitted by a pipe, 19, at the top of the liquid receptacle and flow down one zigzag cooling surface onto a battle, then be directed onto another zig-zag cooling surface until it finally reaches the lowermost surface, 13, from which it will pass through the opening or openings in the lower edge of the partition. The pipe, 19, passes through the rear wall of the liquid receptacle, then extends down through the ice in the outer receptacle and finally passes through the bottom of said outer receptacle so that its lower end may be connected to a barrel or keg, 20, by means of suitable couplings, 21.

Between the front wall, 8, of the inner receptacle and the partition, 14, there is pro vided a short vertical overflow partition, 22, which extends upwardly from the bottom of the inner receptacle. This short partition has its lower edge seated in a horizontal groove in the bottom, 7, and its vertical side edges are engaged at intervals by suitable lugs, 23, on the inner surface of the side walls. A draw-01f pipe, 24, extends from the inner receptacle through the front wall, 8, and also through the ice chamber and outer receptacle, and the outer end of said pipe has a faucet, 25, to control the flow of liquid from the liquid receptacle. On the interior the pipe, 24, extends downwardly between the front wall, 8, and the short partition, 22, and its lower end terminates adjacent to the bottom, 7. A drain pipe, 26, is provided so that all liquid in the liquid receptacle may be drawn off. This pipe will also be utilized during the washing out of said liquid receptacle. A water drain pipe, 27, is also provided so that water from the melting ice may be run off from the outer receptacle Having thus described my invention what I claim and desire to secure by Letters Patent is A liquid cooling apparatus having an outer receptacle with a cover and an inner receptacle also having a cover with an ice space between said two receptacles, the inner receptacle having a rear wall with a plurality of inclined surfaces formed therein and also having a partition extending between the side walls and the cover and bottom which partition is located adjacent to said inclined surfaces and has openings adjacent to its bottom, a plurality of baflie plates carried by the partition and extending in an inclined direction toward the rear wall whereby to project between the inclined surfaces on the latter wall, an overflow partition in the inner receptacle between the front wall and the first-named partition, a liquid supply pipe entering the inner receptacle behind the said first-named partition and an outlet pipe in the inner receptacle between the front wall thereof and the overflow partition therein.

In testimony whereof I aflix my signature in presence of two witnesses.
